Embodiment Construction

[0040] The present invention will be further described below in conjunction with drawings and embodiments.

[0041] A method for predicting peak heating capacity of a heating unit of the present invention comprises the following steps:

[0042] a Data collection link

[0043] This link mainly selects State Grid Energy Xinjiang Fukang Power Generation Co., Ltd. (hereinafter referred to as Lukang Power Plant) as a representative power plant based on the investigation of thermal power plants in Xinjiang. Lukang Power Plant designed two adjustable steam extraction heating units, which were transformed in 2010 to add industrial steam extraction. The rated power of the steam turbine is 150MW. The maximum heating extraction steam capacity of the designed single unit is 130t / h, the pressure is 0.256MPa, and the temperature is 250.1°C; the designed single unit The maximum industrial steam extraction capacity is 30t / h, the pressure is 2.722MPa, and the temperature is 318.5℃. There is ...

Abstract

The invention relates to a method for predicting heating peak modulation capacity of a heat supply unit. The method is characterized by comprising the steps of selecting at least one representative power plant, and performing data collection on heat supply design data, heat supply device conditions, industrial heat load and heating thermal load mediums, parameters and modes of the heat supply unit; through data analysis and theoretical calculation, determining design thermal load and the heat dissipation area of a radiator, considering impact analysis of temperature changes on building heat dissipating capacity and heating capacity, and predicting the heating period peak modulation load of the power plant. The method has the advantages of being scientific, rational and high in practicality. By utilizing the method, the maximum power generating and heat supply potential of the heat supply unit can be brought into full play, and the problem of difficulty in heating period power grid peak modulation is effectively relieved and solved.

Description

technical field [0001] The invention relates to the technical field of heating, and relates to a method for predicting the heating peak regulation capacity of a heating unit. Background technique [0002] With the rapid growth of the installed capacity of the power grid in northern my country and the rapid growth of urban central heating areas, the peak-shaving boilers of thermal power companies have not been configured synchronously, and some heating areas have not even been equipped with peak-shaving boilers, and most or all of the heating tasks have been handed over to The thermal power plant is responsible, so that the generator sets that originally required "heat-electricity linkage" need to "heat-fixed power" to run. In winter, the power load adjustment is limited by the heat load demand, and the peak-shaving capacity of the unit is limited, which greatly affects the heating areas in the north. Grid load balancing. [0003] In the prior art, the focus is usually on how ...
